The 2022 Tucson PHEV pairs a 1.6L turbo four-cylinder with a six-speed automatic and electric motor—a first-year platform that's showing concerning early engine failures related to oil starvation, bearing wear, and thermal stress from the hybrid duty cycle.
Catastrophic Engine Bearing Failure (Theta II GDI)
Occasional · high severity
Typical onset: 30,000-80,000 mi
Symptoms: Rod knock or main bearing rumble on cold start, Metallic rattling under load or acceleration, Low oil pressure warning despite proper oil level, Metal shavings visible in oil during changes
Fix: Complete short block replacement or engine rebuild required—connecting rod bearings and main bearings fail due to oil starvation from the hybrid start/stop cycling and GDI carbon buildup restricting oil passages. 18-24 labor hours for short block, 28-35 hours for full rebuild with machine work.
Estimated cost: $6,500-12,000
Piston Ring Land Cracking and Blowby
Occasional · high severity
Typical onset: 40,000-90,000 mi
Symptoms: Excessive oil consumption (quart per 1,000 miles or worse), Blue smoke on deceleration or startup, Loss of power and rough idle, P0300-series misfire codes across multiple cylinders
Fix: Ring land failure from pre-ignition or LSPI (low-speed pre-ignition) events common to turbocharged GDI engines. Requires full engine disassembly, new pistons and rings, cylinder honing. Often combined with head gasket replacement if caught late. 26-32 labor hours.
Estimated cost: $7,000-10,500
Transmission Oil Cooler Line Leaks
Common · medium severity
Typical onset: 20,000-60,000 mi
Symptoms: Transmission fluid spots under vehicle near front, Burnt smell after highway driving, Harsh shifting or delayed engagement when hot, Low transmission fluid level on dipstick check
Fix: Cooler line fittings crack at crimps or corrode where they meet the radiator-mounted cooler—common on early 2022 builds. Replace lines and top off ATF. 2.5-3.5 hours labor including system flush.
Estimated cost: $450-750
Head Gasket Failure Due to Hybrid Thermal Cycling
Occasional · high severity
Typical onset: 50,000-100,000 mi
Symptoms: Coolant loss with no visible external leaks, White exhaust smoke or sweet smell from tailpipe, Overheating under load despite proper coolant level, Oil milkshake appearance or coolant in expansion tank bubbling
Fix: Hybrid systems cycle the engine on/off constantly, causing repeated thermal expansion/contraction that fatigues head gaskets prematurely. Both head gaskets typically replaced together, includes deck milling if warped. 14-18 labor hours.
Estimated cost: $3,200-5,000
Transmission Mount Collapse
Common · low severity
Typical onset: 35,000-70,000 mi
Symptoms: Clunking on hard acceleration or deceleration, Excessive vibration at idle in Drive, Shifter feels notchy or transmission seems to lurch
Fix: The hydraulic transmission mount can't handle the torque delivery from combined gas and electric power—rubber separates from metal backing. Replace mount, 1.5-2 hours labor.
Estimated cost: $280-450
High-Pressure Fuel Pump and Filter Contamination
Occasional · medium severity
Typical onset: 40,000-80,000 mi
Symptoms: Rough idle or stumbling under boost, P0087 fuel rail pressure too low code, Hard starting after sitting overnight, Reduced power in hybrid launch mode
Fix: GDI high-pressure pump seals leak internally or fuel filter clogs from tank debris—exacerbated by longer intervals between fill-ups on PHEVs. Replace pump and filter together. 3-4 hours labor.
Estimated cost: $900-1,400
Owner tips
Change oil every 4,000 miles MAX—hybrid start/stop is brutal on oil, and these Theta engines are unforgiving of extended intervals
Use Top Tier fuel exclusively and add a can of fuel system cleaner every 5,000 miles to combat GDI carbon buildup on intake valves
Check oil level every other fill-up—consumption issues are an early warning sign of ring or bearing problems
Ensure hybrid battery cooling system is serviced per schedule—overheating the pack changes engine load patterns and accelerates wear
Avoid unless CPO with powertrain warranty intact—too many expensive engine grenades for a 2-year-old design, and repair costs exceed resale value quickly.

Hyundai Motor America (Hyundai) is recalling certain 2022-2024 Tucson vehicles equipped with an optional Mobis tow hitch wiring harness. The wiring harness may have been installed incorrectly, allowing water into the control module. Moisture accumulation may cause the trailer lighting to fail or an electrical short circuit.
Consequence: Nonfunctioning trailer lights can increase the risk of a crash. A short circuit can increase the risk of a fire.
Remedy: Owners are advised to park outside and away from structures until the recall repair is complete. Dealers will install a cap of the wiring, free of charge. Owner notification letters were mailed May 11, 2026. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 290. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov on December 20, 2025.
